Trouble with -lib in linux "undefined reference to `_Dmain'"

Feb 29, 2012

Hi, I use Mono-D and have a hello world example which compiles fine. I set the compiler option "-lib" and receives an error "undefined reference to `_Dmain'". Following commands are generated for the build process: dmd -c "main.d" -of"/home/user/Dokumente/MonoDevelop/HelloWorld/HelloWorld/obj/Debug/main.o" -I"/usr/include/d/dmd/phobos" -I"/usr/include/d/dmd/druntime/import" -gc -debug -lib dmd -gc -debug -of"/home/user/Dokumente/MonoDevelop/HelloWorld/HelloWorld/bin/Debug/HelloWorld" "obj/Debug/main.o" Do I miss an additional linux option or is the order of the commands wrong? Kind regards André

I think you need the -lib in the linker command (too?).
